Well, I can tell you this.
I retrofitted steering wheel with paddles and my S60 was missing the three wires from the SWM to the connector of the shifter on the center console.
I used ohm meter to check the paddles and wiring is correct. When I tested resistance, it did not register any resistance. Paddle shifters are different than button on the shift nob.
The paddles are sharing the ground wire and returning ground signal to two different pins. The circuit always closed, pressing a button cut the circuit on one side. This is how TCM knows up/down shift. If the ground does not return to one of the pins continuedly (circuit is open) . A DTC is generated. The paddle circuit ,might have capacitors or some other component to block back flow from other side.
I a, mot sure what you are trying to achieve those paddles are cheap but anyway. Good luck
